Install MATE on top of Unity

Installing MATE is as easy. First, add the MATE repository to your system & update your repository information:

sudo add-apt-repository "deb http://packages.mate-desktop.org/repo/ubuntu $(lsb_release -sc) main" && sudo apt-get update

Install the MATE keyring to avoid any future authentication errors, and update again:

sudo apt-get install mate-archive-keyring && sudo apt-get update

Then install MATE:

sudo apt-get install mate-core # This installs the base environment

sudo apt-get install mate-desktop-environment # This installs the whole environment

Now it’s as easy as logging into a MATE session and run GNOME Shell atop the MATE environment, or running MATE Panel from within GNOME Shell or Unity for that matter:

Despite a little overlap, with auto-hide and a matching theme, no one would know.
